All mistletoes grow as parasites on the branches of trees and shrubs. ... When a mistletoe seed lands on a suitable host, it sends out roots that penetrate the tree and draw on its nutrients and water. Mistletoes also can produce energy through photosynthesis in their green leaves.

What kind of tree does mistletoe grow in?

Mistletoe species have evolved to plant themselves on hosts ranging from pine trees to cacti, but the species most commonly associated with European-based mistletoe mythologies (like kissing beneath it on Christmas) are typically found on large deciduous trees, like oaks.

How does mistletoe spread?

Most mistletoe seeds are spread by birds, which eat the berries and defecate on tree branches. If attached to a new host tree, the parasitic seed releases a compound called “viscin”, which dries to form a stiff biological cement.
